is a prohibited practice in competitive sports with potential adverse effects; therefore, it is crucial to describe the attitudes of athletes towards this behavior and to determine which o these increase the susceptibility to carry out this practice. Objective: To determine the attitude of high-performance athletes towards doping in a sports institute in the city of Medellin, Colombia. Methods: We performed a cross-sectional study during 2016, with a sample taken to convenience consisting of athletes over 18 years old enrolled in a sports institute of the city of Medellin (Colombia). The athletes filled by themselves the Petroczi and Aidman questionnaire: Performance Enhancement Attitude Scale (PEAS) adapted to the Spanish language by Morente-Sánchez et al. This scale has 17 items with likert answer options, with a score ranging from 1 to 6, with a higher score indicating a stronger tendency towards doping practices. Results: 112 athletes were included with an average age of 21.6 years old, a 60% of them were male and the most frequent sports were karate 17%, judo 12.5% and athletics 9.8%. The average score of the questionnaire was 35.5 points of a 102 possible points. The lowest score was obtained in the following items: Is Doping necessary 1,4 and Doping isn’t cheating, everyone does it 1,5. Conclusion: In our population, there is a low tendency towards doping practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sports" title="sports">sports</a>, <a href="https://publications.waset.org/abstracts/search?q=doping%20in%20sports" title=" doping in sports"> doping in sports</a>, <a href="https://publications.waset.org/abstracts/search?q=athletic%20performance" title=" athletic performance"> athletic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=attitude" title=" attitude"> attitude</a> </p> <a href="https://publications.waset.org/abstracts/93827/attitude-towards-doping-of-high-performance-athletes-in-a-sports-institute-of-the-city-of-medellin-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93827.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">230</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1478</span> Prevalence and Characteristics of Consumption of Nutraceuticals: The Case Study of Undergraduate Students of Medellin- Colombia, 2013</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gloria%20In%C3%A9s%20Mart%C3%ADnez%20Dom%C3%ADnguez">Gloria Inés Martínez Domínguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez%20S%C3%A1nchez"> Lina María Martínez Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20de%20los%20%C3%81ngeles%20Rodr%C3%ADguez%20G%C3%A1zquez"> María de los Ángeles Rodríguez Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Guillermo%20Jim%C3%A9nez%20Jim%C3%A9nez"> Juan Guillermo Jiménez Jiménez</a>, <a href="https://publications.waset.org/abstracts/search?q=Johan%20Sebasti%C3%A1n%20Lopera%20Valle"> Johan Sebastián Lopera Valle</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Vargas%20Grisales"> Natalia Vargas Grisales</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Rojas%20Jim%C3%A9nez"> Sara Rojas Jiménez</a>, <a href="https://publications.waset.org/abstracts/search?q=Alejandra%20Uribe%20Ocampo"> Alejandra Uribe Ocampo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Correa%20P%C3%A9rez"> Sara Correa Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Perilla%20Hern%C3%A1ndez"> Natalia Perilla Hernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Sebasti%C3%A1n%20Mar%C3%ADn%20C%C3%A1rdenas"> Juan Sebastián Marín Cárdenas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The relationship between diet and chronic or degenerative diseases has led to the development of functional foods such as nutraceuticals.

It was a simple random sampling with the Statcalc EpiInfo software vr 6.04. It was designed an instrument for collection of demographic data and consumption of nutraceuticals. Statistical analysis used the SPSS program. Results: 427 students, average age 20.8 years (SD 3.1), 56.1% were women. The life prevalence of nutraceuticals consumption was 66.3% and the annual 51.8%. The main reasons for consumption were as food complement 32.8% and prevent diseases 20.1%. Conclusion: The high prevalence of nutraceuticals observed is comparable to that reported in the literature, which suggests an increasing trend in the habit of consumption of dietary supplement which have a preventive or protective effect on health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dietary%20supplements" title="dietary supplements">dietary supplements</a>, <a href="https://publications.waset.org/abstracts/search?q=food" title=" food"> food</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20food" title=" functional food"> functional food</a>, <a href="https://publications.waset.org/abstracts/search?q=Colombia" title=" Colombia"> Colombia</a> </p> <a href="https://publications.waset.org/abstracts/1597/prevalence-and-characteristics-of-consumption-of-nutraceuticals-the-case-study-of-undergraduate-students-of-medellin-colombia-2013" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1597.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">577</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1477</span> Use of Alternative and Complementary Therapies in Patients with Chronic Pain in a Medical Institution in Medellin, Colombia, 2014</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez%20S%C3%A1nchez">Lina María Martínez Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juliana%20Molina%20Valencia"> Juliana Molina Valencia</a>, <a href="https://publications.waset.org/abstracts/search?q=Esteban%20Vallejo%20Agudelo"> Esteban Vallejo Agudelo</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Gallego%20Gonz%C3%A1lez"> Daniel Gallego González</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Isabel%20P%C3%A9rez%20Palacio"> María Isabel Pérez Palacio</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Ricardo%20Gaviria%20Garc%C3%ADa"> Juan Ricardo Gaviria García</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20De%20Los%20%C3%81ngeles%20Rodr%C3%ADguez%20G%C3%A1zquez"> María De Los Ángeles Rodríguez Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Gloria%20In%C3%A9s%20Mart%C3%ADnez%20Dom%C3%ADnguez"> Gloria Inés Martínez Domínguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Alternative and complementary therapies constitute a vast and complex combination of interventions, philosophies, approaches, and therapies that acquire a holistic healthcare point of view, becoming an alternative for the treatment of patients with chronic pain. Objective: determine the characteristics of the use of alternative and complementary therapies in patients with chronic pain who consulted in a medical institution. Methodology: cross-sectional and descriptive study, with a population of patients that assisted to the outpatient consultation and met the eligibility criteria. Sampling was not conducted. A form was used for the collection of demographic and clinical variables and the Holistic Complementary and Alternative Medicine Questionnaire (HCAMQ) was validated. The analysis and processing of information was carried out using the SPSS program vr.19. Results: 220 people with chronic pain were included. The average age was 54.7±16.2 years, 78.2% were women, and 75.5% belonged to the socioeconomic strata 1 to 3. Musculoskeletal pain (77.7%), migraine (15%) and neuralgia (9.1%) were the most frequently types of chronic pain. 33.6% of participants have used some kind of alternative and complementary therapy; the most frequent were: homeopathy (14.5%), phytotherapy (12.7%), and acupuncture (11.4%). The total average HCAMQ score for the study group was 30.2±7.0 points, which shows a moderate attitude toward the use of complementary and alternative medicine. The highest scores according to the type of pain were: neuralgia (32.4±5.8), musculoskeletal pain (30.5±6.7), fibromyalgia (29.6±7.3) and migraine (28.5±8.8). The reliability of the HCAMQ was acceptable (Cronbach's α: 0.6). Conclusion: it was noted that the types of chronic pain and the clinical or therapeutic management of patients correspond to the data available in current literature. Despite the moderate attitude toward the use of these alternative and complementary therapies, one of every three patients uses them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chronic%20pain" title="chronic pain">chronic pain</a>, <a href="https://publications.waset.org/abstracts/search?q=complementary%20therapies" title=" complementary therapies"> complementary therapies</a>, <a href="https://publications.waset.org/abstracts/search?q=homeopathy" title=" homeopathy"> homeopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=acupuncture%20analgesia" title=" acupuncture analgesia"> acupuncture analgesia</a> </p> <a href="https://publications.waset.org/abstracts/41720/use-of-alternative-and-complementary-therapies-in-patients-with-chronic-pain-in-a-medical-institution-in-medellin-colombia-2014" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41720.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">515</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1476</span> Chromosomal Damage in Human Lymphocytes by Ultraviolet Radiation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Osorio%20Ospina">Felipe Osorio Ospina</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Adelaida%20Mejia%20Arango"> Maria Adelaida Mejia Arango</a>, <a href="https://publications.waset.org/abstracts/search?q=Esteban%20On%C3%A9simo%20Vallejo%20Agudelo"> Esteban Onésimo Vallejo Agudelo</a>, <a href="https://publications.waset.org/abstracts/search?q=Victoria%20Luc%C3%ADa%20D%C3%A1vila%20Osorio"> Victoria Lucía Dávila Osorio</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Vargas%20Grisales"> Natalia Vargas Grisales</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez%20Sanchez"> Lina María Martínez Sanchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Andr%C3%A9s%20Agudelo%20V%C3%A9lez"> Camilo Andrés Agudelo Vélez</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81ngela%20Maria%20Londo%C3%B1o%20Garc%C3%ADa"> Ángela Maria Londoño García</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Cristina%20Ortiz%20Trujillo"> Isabel Cristina Ortiz Trujillo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Excessive exposure to ultraviolet radiation, has shown to be a risk factor for photodamage, alteration of the immune mechanisms to recognize malignant cells and cutaneous pro-inflamatorios States and skin cancers. Objective: Identify the time of exposure to ultraviolet radiation for the production of chromosomal damage in human lymphocytes. Methodology: We conducted an in vitro study serial, in which samples were taken from heparinized blood of healthy people, who do not submit exposure to agents that could induce chromosomal alterations. The samples were cultured in RPMI-1640 medium containing 10% fetal bovine serum, penicillin and streptomycin antibiotic. Subsequently, they were grouped and exposed to ultraviolet light for 1 to 20 seconds. At the end of the treatments, cytology samples were prepared, and it was colored with Giemsa (5%). Reading was carried out in an optical microscope and 100 metaphases analysed by treatment for posting chromosomal alterations. Each treatment was conducted at three separate times and each became two replicas. Results: We only presented chromosomal alterations in lymphocytes exposed to UV for a groups 1 to 3 seconds (p<0.05). Conclusions: Exposure to ultraviolet radiation generates visible damage in chromosomes from human lymphocytes observed in light microscopy, the highest rates of injury was observed between two and three seconds, and above this value, the reduction in the number of mitotic cells was evident. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultraviolet%20rays" title="ultraviolet rays">ultraviolet rays</a>, <a href="https://publications.waset.org/abstracts/search?q=lymphocytes" title=" lymphocytes"> lymphocytes</a>, <a href="https://publications.waset.org/abstracts/search?q=chromosome%20breakpoints" title=" chromosome breakpoints"> chromosome breakpoints</a>, <a href="https://publications.waset.org/abstracts/search?q=photodamage" title=" photodamage"> photodamage</a> </p> <a href="https://publications.waset.org/abstracts/14162/chromosomal-damage-in-human-lymphocytes-by-ultraviolet-radiation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14162.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">428</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1475</span> Ultraviolet Radiation and Chromosomal Damage in Human Lymphocytes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Osorio%20Ospina">Felipe Osorio Ospina</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Adelaida%20Mejia%20Arango"> Maria Adelaida Mejia Arango</a>, <a href="https://publications.waset.org/abstracts/search?q=Esteban%20On%C3%A9simo%20Vallejo%20Agudelo"> Esteban Onésimo Vallejo Agudelo</a>, <a href="https://publications.waset.org/abstracts/search?q=Victoria%20Luc%C3%ADa%20D%C3%A1vila%20Osorio"> Victoria Lucía Dávila Osorio</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Vargas%20Grisales"> Natalia Vargas Grisales</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez%20Sanchez"> Lina María Martínez Sanchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Andr%C3%A9s%20Agudelo%20V%C3%A9lez"> Camilo Andrés Agudelo Vélez</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81ngela%20Maria%20Londo%C3%B1o%20Garc%C3%ADa"> Ángela Maria Londoño García</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Cristina%20Ortiz%20Trujillo"> Isabel Cristina Ortiz Trujillo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Excessive exposure to ultraviolet radiation, has shown to be a risk factor for photodamage, alteration of the immune mechanisms to recognize malignant cells and cutaneous pro-inflamatorios states and skin cancers.

Conclusions: Exposure to ultraviolet radiation generates visible damage in chromosomes from human lymphocytes observed in light microscopy, the highest rates of injury was observed between two and three seconds, and above this value, the reduction in the number of mitotic cells was evident. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chromosome%20breakpoints" title="chromosome breakpoints">chromosome breakpoints</a>, <a href="https://publications.waset.org/abstracts/search?q=lymphocytes" title=" lymphocytes"> lymphocytes</a>, <a href="https://publications.waset.org/abstracts/search?q=photodamage" title=" photodamage"> photodamage</a>, <a href="https://publications.waset.org/abstracts/search?q=ultraviolet%20rays" title=" ultraviolet rays"> ultraviolet rays</a> </p> <a href="https://publications.waset.org/abstracts/26760/ultraviolet-radiation-and-chromosomal-damage-in-human-lymphocytes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26760.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">578</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1474</span> Characterization of Chest Pain in Patients Consulting to the Emergency Department of a Health Institution High Level of Complexity during 2014-2015, Medellin, Colombia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Iv%C3%A1n%20Ba%C3%B1ol-Betancur">Jorge Iván Bañol-Betancur</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez-S%C3%A1nchez"> Lina María Martínez-Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20de%20los%20%C3%81ngeles%20Rodr%C3%ADguez-G%C3%A1zquez"> María de los Ángeles Rodríguez-Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Estefan%C3%ADa%20Bahamonde-Olaya"> Estefanía Bahamonde-Olaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Mar%C3%ADa%20Guti%C3%A9rrez-Tamayo"> Ana María Gutiérrez-Tamayo</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Isabel%20Jaramillo-Jaramillo"> Laura Isabel Jaramillo-Jaramillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Ruiz-Mej%C3%ADa"> Camilo Ruiz-Mejía</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Morales-Quintero"> Natalia Morales-Quintero</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Acute chest pain is a distressing sensation between the diaphragm and the base of the neck and it represents a diagnostic challenge for any physician in the emergency department. Objective: To establish the main clinical and epidemiological characteristics of patients who present with chest pain to the emergency department in a private clinic from the city of Medellin, during 2014-2015. Methods: Cross-sectional retrospective observational study. Population and sample were patients who consulted for chest pain in the emergency department who met the eligibility criteria. The information was analyzed in SPSS program vr.21; qualitative variables were described through relative frequencies, and the quantitative through mean and standard deviation ‬or medians according to their distribution in the study population. Results: A total of 231 patients were evaluated, the mean age was 49.5 ± 19.9 years, 56.7% were females. The most frequent pathological antecedents were hypertension 35.5%, diabetes 10,8%, dyslipidemia 10.4% and coronary disease 5.2%. Regarding pain features, in 40.3% of the patients the pain began abruptly, in 38.2% it had a precordial location, for 20% of the cases physical activity acted as a trigger, and 60.6% was oppressive. Costochondritis was the most common cause of chest pain among patients with an established etiologic diagnosis, representing the 18.2%. Conclusions: Although the clinical features of pain reported coincide with the clinical presentation of an acute coronary syndrome, the most common cause of chest pain in study population was costochondritis instead, indicating that it is a differential diagnostic in the approach of patients with pain acute chest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20coronary%20syndrome" title="acute coronary syndrome">acute coronary syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=chest%20pain" title=" chest pain"> chest pain</a>, <a href="https://publications.waset.org/abstracts/search?q=epidemiology" title=" epidemiology"> epidemiology</a>, <a href="https://publications.waset.org/abstracts/search?q=osteochondritis" title=" osteochondritis"> osteochondritis</a> </p> <a href="https://publications.waset.org/abstracts/71857/characterization-of-chest-pain-in-patients-consulting-to-the-emergency-department-of-a-health-institution-high-level-of-complexity-during-2014-2015-medellin-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71857.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">343</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1473</span> Clinical and Epidemiological Profile of Patients with Chronic Obstructive Pulmonary Disease in a Medical Institution from the City of Medellin, Colombia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Andres%20Agudelo-Velez">Camilo Andres Agudelo-Velez</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Martinez-Sanchez"> Lina María Martinez-Sanchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Perilla-Hernandez"> Natalia Perilla-Hernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20De%20Los%20Angeles%20Rodriguez-Gazquez"> Maria De Los Angeles Rodriguez-Gazquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Hernandez-Restrepo"> Felipe Hernandez-Restrepo</a>, <a href="https://publications.waset.org/abstracts/search?q=Dayana%20Andrea%20Quintero-Moreno"> Dayana Andrea Quintero-Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Ruiz-Mejia"> Camilo Ruiz-Mejia</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Cristina%20Ortiz-Trujillo"> Isabel Cristina Ortiz-Trujillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Monica%20Maria%20Zuluaga-Quintero"> Monica Maria Zuluaga-Quintero</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chronic obstructive pulmonary disease is common condition, characterized by a persistent blockage of airflow, partially reversible and progressive, that represents 5% of total deaths around the world, and it is expected to become the third leading cause of death by 2030.

Objective: Determine clinical and sociodemographic variables in women with preeclampsia. Methods: This cross-sectional study enrolled 50 patients with the diagnosis of preeclampsia, from a private institution in Medellin, during 2015. We used the software SPSS ver.20 for statistical analysis. For the qualitative variables, we calculated the mean and standard deviation, while, for ordinal and nominal levels of quantitative variables, ratios were estimated. Results: The average age was 26.8±5.9 years. The predominant characteristics were socioeconomic stratum 2 (48%), students (55%), mixed race (46%) and middle school as level of education (38%). As for clinical features, 72% of the cases were mild preeclampsia, and 22% were severe forms. The most common clinical manifestations were edema (46%), headache (62%), and proteinuria (55%). As for the Gyneco-obstetric history, 8% reported previous episodes of this disease and it was the first pregnancy for 60% of the patients. Conclusions: Preeclampsia is a frequent condition in young women; on the other hand, headache and edema were the most common reasons for consultation, therefore, doctors need to be aware of these symptoms in pregnant women. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pre-eclampsia" title="pre-eclampsia">pre-eclampsia</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertension" title=" hypertension"> hypertension</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy%20complications" title=" pregnancy complications"> pregnancy complications</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title=" pregnancy"> pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=abdominal" title=" abdominal"> abdominal</a>, <a href="https://publications.waset.org/abstracts/search?q=edema" title=" edema"> edema</a> </p> <a href="https://publications.waset.org/abstracts/46372/clinical-and-epidemiological-profile-in-patients-with-preeclampsia-in-a-private-institution-in-medellin-colombia-2015" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46372.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">363</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1471</span> Epidemiological and Clinical Profile of Patients with Chorioamnionitis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Cristina%20Ortiz%20Trujillo">Isabel Cristina Ortiz Trujillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Maria%20Martinez%20Sanchez"> Lina Maria Martinez Sanchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Hern%C3%A1ndez%20Restrepo"> Felipe Hernández Restrepo</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Gallego%20Gonzalez"> Daniel Gallego Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Vargas%20Grisales"> Natalia Vargas Grisales</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Andr%C3%A9s%20Agudelo%20V%C3%A9lez"> Camilo Andrés Agudelo Vélez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chorioamnionitis, is a pregnancy infection, causes different fetal and maternal symptoms.

To assess the overall economic impact of the disease, out-of-pocket and indirect costs are also required. This research is aimed to estimate overall economic impact under DOTS-strategy (Directly Observed Therapy Short Course). Methods: A cross-sectional survey of 91 adult tuberculosis patients in treatment for at least two months was conducted from the society perspective. A standardized questionnaire was used in three different cities of Colombia: Medellin (poverty is 17.7%), Monteria (poverty is 36.9%) and Quibdó (poverty is 51.2%). Costs were converted to 2013 USD and categorized into two periods: diagnostics phase and treatment. Results: The median cost during diagnostics was 13$ (±SD 9.5). The median monthly patient out-of-pocket costs during treatment were 32$ (±SD 6.8), equivalent to 17% of patient’s median monthly income, estimated in 186$ (±SD 23). Costs recorded in Medellin were 47$ in Monteria was 18$ and in Quibdó was 13$. Conclusion: Patient costs under DOTS strategy are high even when services are provided free of charge. The creation or strengthening of community-based treatment supervisors could greatly impact costs of tuberculosis and lower drop-outs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title="tuberculosis">tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=costs%20and%20cost%20analysis" title=" costs and cost analysis"> costs and cost analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20promotion" title=" health promotion"> health promotion</a>, <a href="https://publications.waset.org/abstracts/search?q=Colombia" title=" Colombia"> Colombia</a> </p> <a href="https://publications.waset.org/abstracts/5825/out-of-pocket-costs-for-patients-with-tuberculosis-in-colombia-evidence-from-three-metropolitan-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5825.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">367</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1469</span> Comparative Analysis of Three Types of Recycled Aggregates and its Use in Masonry Mortar Fabrication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariano%20Gonzalez%20Cortina">Mariano Gonzalez Cortina</a>, <a href="https://publications.waset.org/abstracts/search?q=Pablo%20Saiz%20Martinez"> Pablo Saiz Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20%20Fernandez%20Martinez"> Francisco Fernandez Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Rodriguez%20Sanchez"> Antonio Rodriguez Sanchez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Construction sector incessant activity of the last years preceding the crisis has originated a high waste generation and an increased use of raw materials. The main aim of this research is to compare three types of recycled aggregates and the feasibility to incorporate them into masonry mortar fabrication. The tests were developed using two types of binders: CEM II/B-L 32.5 N and CEM IV/B (V) 32.5 N. 50%, 75% and 100% of natural sand were replaced with three types of recycled aggregates. Cement-to-aggregate by dry weight proportions were 1:3 and 1:4. Physical and chemical characterization of recycled aggregates showed continues particle size distribution curve, lower density and higher absorption, which was the reason to use additive to obtain required mortar consistency. Main crystalline phases determined in the X-Ray diffraction test were calcite, quartz, and gypsum. Performed tests show that cement-based mortars fabricated with CEM IV/B (V) 32. 5 N can incorporate recycled aggregates coming from ceramic, concrete and mixed recycling processes, using 1:3 and 1:4 cement-to-aggregate proportions, complying with the limits established by the Spanish standards. It was concluded that recycled mortar coming from concrete recycling process is the one which presents better characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20and%20demolition%20waste" title="construction and demolition waste">construction and demolition waste</a>, <a href="https://publications.waset.org/abstracts/search?q=masonry%20mortar" title=" masonry mortar"> masonry mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20aggregate" title=" recycled aggregate"> recycled aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20treatment" title=" waste treatment"> waste treatment</a> </p> <a href="https://publications.waset.org/abstracts/52696/comparative-analysis-of-three-types-of-recycled-aggregates-and-its-use-in-masonry-mortar-fabrication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52696.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">423</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1468</span> Toxic Masculinity as Dictatorship: Gender and Power Struggles in Tomás Eloy Martínez´s Novels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariya%20Dzhyoyeva">Mariya Dzhyoyeva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present paper, I examine manifestations of toxic masculinity in the novels by Tomás Eloy Martínez, a post-Boom author, journalist, literary critic, and one of the representatives of the Argentine writing diaspora. I focus on the analysis of Martínez´s characters that display hypermasculine traits to define the relationship between toxic masculinity and power, including the power of authorship and violence as they are represented in his novels. The analysis reveals a complex network in which gender, power, and violence are intertwined and influence and modify each other. As the author exposes toxic masculine behaviors that generate violence, he looks to undermine them. Departing from M. Kimmel´s idea of masculinity as homophobia, I examine how Martínez “outs” his characters by incorporating into the narrative some secret, privileged sources that provide alternative accounts of their otherwise hypermasculine lives. These background stories expose their “weaknesses,” both physical and mental, and thereby feminize them in their own eyes. In a similar way, the toxic masculinity of the fictional male author that wields his power by abusing the written word as he abuses the female character in the story is exposed as a complex of insecurities accumulated by the character due to his childhood trauma. The artistic technique that Martínez uses to condemn the authoritarian male behavior is accessing his subjectivity and subverting it through a multiplicity of identities. Martínez takes over the character’s “I” and turns it into a host of pronouns with a constantly shifting point of reference that distorts not only the notions of gender but also the very notion of identity. In doing so, he takes the character´s affirmation of masculinity to the limit where the very idea of it becomes unsustainable. Viewed in the context of Martínez´s own exilic story, the condemnation of toxic masculine power turns into the condemnation of dictatorship and authoritarianism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender" title="gender">gender</a>, <a href="https://publications.waset.org/abstracts/search?q=masculinity." title=" masculinity."> masculinity.</a>, <a href="https://publications.waset.org/abstracts/search?q=toxic%20masculinity" title=" toxic masculinity"> toxic masculinity</a>, <a href="https://publications.waset.org/abstracts/search?q=authoritarian" title=" authoritarian"> authoritarian</a>, <a href="https://publications.waset.org/abstracts/search?q=Argentine%20literature" title=" Argentine literature"> Argentine literature</a>, <a href="https://publications.waset.org/abstracts/search?q=Mart%C3%ADnez" title=" Martínez"> Martínez</a> </p> <a href="https://publications.waset.org/abstracts/163345/toxic-masculinity-as-dictatorship-gender-and-power-struggles-in-tomas-eloy-martinezs-novels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163345.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">71</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1467</span> Flow Visualization in Biological Complex Geometries for Personalized Medicine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Escobar-del%20Pozo">Carlos Escobar-del Pozo</a>, <a href="https://publications.waset.org/abstracts/search?q=C%C3%A9sar%20Ahumada-Monroy"> César Ahumada-Monroy</a>, <a href="https://publications.waset.org/abstracts/search?q=Azael%20Garc%C3%ADa-Rebolledo"> Azael García-Rebolledo</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20Brambila-Sol%C3%B3rzano"> Alberto Brambila-Solórzano</a>, <a href="https://publications.waset.org/abstracts/search?q=Gregorio%20Mart%C3%ADnez-S%C3%A1nchez"> Gregorio Martínez-Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Ortiz-Rinc%C3%B3n"> Luis Ortiz-Rincón</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Numerical simulations of flow in complex biological structures have gained considerable attention in the last years.

Cali, the third largest city in the country, is characterized by a high percentage of socially and economically vulnerable population groups who take part in the urban informal economy, with street vending as their primary source of income. This paper studies the socio-economic dimensions of street vendors in Cali. In particular, it examines why they are unable to capitalize on their comparatively high earnings and are not likely to escape poverty even though they usually profit from government welfare and tax evasion due to the non-regulated character of informality. The analysis of an observational study and two surveys with 637 and 300 participants show that street vending is a cash-based day-to-day activity. Since most of the street vendors do not have access to formal banking systems, they depend on payday loans with incomparably high interest rates which absorb a large share of their income and maintain a continuous indebtedness. This is one of the main reasons why they are unable to improve their living conditions. However, the daily cash flow masks the high opportunity cost of loans and long-term deficits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Colombia" title="Colombia">Colombia</a>, <a href="https://publications.waset.org/abstracts/search?q=informal%20economy" title=" informal economy"> informal economy</a>, <a href="https://publications.waset.org/abstracts/search?q=payday%20loans" title=" payday loans"> payday loans</a>, <a href="https://publications.waset.org/abstracts/search?q=street%20vendors" title=" street vendors"> street vendors</a> </p> <a href="https://publications.waset.org/abstracts/71049/debt-portfolios-of-the-poor-the-case-of-street-vendors-in-cali-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71049.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">324</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1464</span> Effect of Carbon Additions on FeCrNiMnTi High Entropy Alloy </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20D.%20Gomez-Esparza">C.

The HEA field has promoted the exploration of several compositions including the addition of non-metallic elements like carbon, which in traditional metallurgy is mainly used in the steel industry. The aim of this work was the synthesis of equiatomic FeCrNiMnTi high entropy alloys, with minor carbon content, by mechanical alloying and sintering. The effect of the addition of carbon nanotubes and graphite were evaluated by X-ray diffraction, scanning electron microscopy, and microhardness test. The structural and microstructural characteristics of the equiatomic alloys, as well as their hardness were compared with those of an austenitic AISI 321 stainless steel processed under the same conditions. The results showed that porosity in bulk samples decreases with carbon nanotubes addition, while the equiatomic composition favors the formation of titanium carbide and increased the AISI 321 hardness more than three times. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotubes" title="carbon nanotubes">carbon nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=graphite" title=" graphite"> graphite</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20entropy%20alloys" title=" high entropy alloys"> high entropy alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20alloying" title=" mechanical alloying"> mechanical alloying</a> </p> <a href="https://publications.waset.org/abstracts/87464/effect-of-carbon-additions-on-fecrnimnti-high-entropy-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87464.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">198</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1463</span> Verifying Environmental Performance through Inventory and Assessment: Case Study of the Los Alamos National Laboratory Waste Compliance and Tracking System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oral%20S.%20Saulters">Oral S.

The period prior to that Constitution, which marked the transition to democracy, was marked by National Catholicism, which actively limited the existence of religions other than Catholicism in the national territory. The approval of this norm allowed the opening in many aspects, including the religious one. This work will profusely describe the evolution of the appearance of religious minorities in Spain from the moment of the transition, in which the space for religious freedom appears up to the present. The methodology is twofold. On the one hand, qualitative analysis of the legislation has allowed the religious opening. On the other, the quantitative analysis of the NMRs implemented in Spain. The entire analysis establishes the increase in religious organizations as a result, with notable variations across the territory. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=new%20religious%20movements" title="new religious movements">new religious movements</a>, <a href="https://publications.waset.org/abstracts/search?q=religious%20minorities" title=" religious minorities"> religious minorities</a>, <a href="https://publications.waset.org/abstracts/search?q=sociological%20analysis" title=" sociological analysis"> sociological analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Spain" title=" Spain"> Spain</a> </p> <a href="https://publications.waset.org/abstracts/156551/sociological-review-of-the-implantation-of-new-religious-movements-in-spain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156551.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1461</span> Multidimensional Item Response Theory Models for Practical Application in Large Tests Designed to Measure Multiple Constructs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Fernanda%20Ordo%C3%B1ez%20Martinez">Maria Fernanda Ordoñez Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Alvaro%20Mauricio%20Montenegro"> Alvaro Mauricio Montenegro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work presents a statistical methodology for measuring and founding constructs in Latent Semantic Analysis.

In order to cover this goal, it has been considered four different indexes of service quality in the air transportation industry, and also two indicators of economic performance, revenues and return on investment (ROI). Data from American airline companies over a period that covers from 2006 to 2013 have been used in order to determine if airlines’ profitability increases when service quality improves. Considering the effects on airlines’ profitability, the results confirm the positive and significant influence of service quality on the ROI of the companies in our study. Meanwhile, a non-significant effect was found for airline revenues related to quality. No previous research in this area has been done and these findings could encourage airline companies to invest in quality as far as this policy can have a return on their profitability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airlines" title="airlines">airlines</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20performance" title=" economic performance"> economic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=key%20performance%20indicators" title=" key performance indicators"> key performance indicators</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a> </p> <a href="https://publications.waset.org/abstracts/36920/us-airlines-performance-and-its-connection-with-service-quality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36920.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">473</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1459</span> Study of the Influence of the Different Treatments in Almond Shell-Based Masterbatches</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Ib%C3%A1%C3%B1ez">A.

These innovative masterbatches have 20 wt % of the almond shell. Different treatments were carried out with sodium hydroxide (NaOH) and maleic anhydride (MA) to obtain better interfacial bonding between fibre and matrix. The masterbatches were produced by varying the fibre treatments (type of treatment, concentration and temperature). The masterbatches have been injected to obtain standardised test samples in order to study mechanical properties. The results show that, the some of the treated fibres present slightly higher flexural modulus and impact strength than untreated fibres. This study is part of a LIFE project (MASTALMOND) aimed to create and test at preindustrial level new coloured masterbatches based on biodegradable polymers and containing in its formulation a high percentage of almond shell, a natural waste material, which firstly will permit to cover technical requirements of two traditional industrial sectors: toy and furniture, although the results achieved could be extended to other industrial sectors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additivation" title="additivation">additivation</a>, <a href="https://publications.waset.org/abstracts/search?q=almond%20shell" title=" almond shell"> almond shell</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradable" title=" biodegradable"> biodegradable</a>, <a href="https://publications.waset.org/abstracts/search?q=masterbatch" title=" masterbatch"> masterbatch</a>, <a href="https://publications.waset.org/abstracts/search?q=PLA" title=" PLA"> PLA</a>, <a href="https://publications.waset.org/abstracts/search?q=injection%20moulding" title=" injection moulding "> injection moulding </a> </p> <a href="https://publications.waset.org/abstracts/18973/study-of-the-influence-of-the-different-treatments-in-almond-shell-based-masterbatches" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18973.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">426</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1458</span> Effects of COVID-19 Confinement on Physical Activity and Screen Time in Spanish Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Medrano">Maria Medrano</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Cadenas-Sanchez"> Cristina Cadenas-Sanchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Maddi%20Oses"> Maddi Oses</a>, <a href="https://publications.waset.org/abstracts/search?q=Lide%20Arenaza"> Lide Arenaza</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Amasene"> Maria Amasene</a>, <a href="https://publications.waset.org/abstracts/search?q=Idoia%20Labayen"> Idoia Labayen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The COVID-19 outbreak began in December 2019 in China and was rapidly expanded globally. Emergency measures, such as social distance or home confinement, were adopted by many country governments to prevent its transmission. In Spain, one of the most affected countries, the schools were closed, and one of the most severe mandatory home confinement was established for children from 14th March to 26th April 2020. The hypothesis of this study was that the measures adopted during the COVID-19 pandemic may have negatively affected physical activity and screen time of children. However, few studies have examined the effects of COVID-19 pandemic on lifestyle behaviours. Thus, the aim of the current work was to analyse the effects of the COVID-19 confinement on physical activity and screen time in Spanish children. For the current purpose, a total of 113 children and adolescents (12.0 ± 2.6 yr., 51.3% boys, 24.0% with overweight/obesity according to the World Obesity Federation) of the MUGI project were included in the analyses. Physical activity and screen time were longitudinally assessed by 'The Youth Activity Profile' questionnaire (YAP). Differences in physical activity and screen time before and during the confinement were assessed by dependent t-test. Before the confinement, 60% did not meet physical activity recommendations ( ≥ 60/min/day of moderate to vigorous physical activity), and 61% used screens ≥ 2 h/day. During the COVID-19 confinement, children decreased their physical activity levels (-91 ± 55 min/day, p < 0.001) and increased screen time ( ± 2.6 h/day, p < 0.001). The prevalence of children that worsened physical activity and screen time during the COVID-19 confinement were 95.2% and 69.8%, respectively. The current study evidence the negative effects of the COVID-19 confinement on physical activity and screen time in Spanish children. These findings should be taken into account to develop and implement future public health strategies for preserving children's lifestyle behaviours and health during and after the COVID-19 pandemic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title="COVID-19">COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=lifestyle%20changes" title=" lifestyle changes"> lifestyle changes</a>, <a href="https://publications.waset.org/abstracts/search?q=paediatric" title=" paediatric"> paediatric</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activity" title=" physical activity"> physical activity</a>, <a href="https://publications.waset.org/abstracts/search?q=screen%20time" title=" screen time"> screen time</a> </p> <a href="https://publications.waset.org/abstracts/128256/effects-of-covid-19-confinement-on-physical-activity-and-screen-time-in-spanish-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128256.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">132</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1457</span> Photoreflectance Anisotropy Spectroscopy of Coupled Quantum Wells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20V.%20Gonzalez%20Fernandez">J.

There are listed 43 genera for Colombia but without a specific number of their species. No species of the genus Agriotes Eschscholtz (Elaterinae: Agriotini) have been recorded in Colombia. Currently, the subtribe Agriotina in the New World includes three genera: Agriotes, Bohartina Arias and Dalopius Eschscholtz. Historically, the genera Agriotes and Dalopius have had significant taxonomic problems due to their morphological resemblance. These similarities motivated several specialists to generate taxonomic movements such as synonyms and segregations of species in these genera on several occasions. To trying to solve these taxonomic problems, an author proposes some morphological characters present in the larvae, but mainly some genital characters of the females, such as the sclerotized plates of the bursa copulatrix. After examining material newly collected in Colombia, we found a click beetle having a unique combination of diagnostic characters that clearly separate it from any other genera of Agriotina. Hence, we describe and illustrate this click beetle under the name Raphaellus deusminutosi Zurita-García, Morales-Perdomo & Martínez-Luque n. gen. & n. sp., and we also compare this genus with the other New World genera of the subtribes Agriotina. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=click%20beetles" title="click beetles">click beetles</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20genus" title=" new genus"> new genus</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20species" title=" new species"> new species</a>, <a href="https://publications.waset.org/abstracts/search?q=elaterinae" title=" elaterinae"> elaterinae</a>, <a href="https://publications.waset.org/abstracts/search?q=raphaellus%20deusminutosi" title=" raphaellus deusminutosi"> raphaellus deusminutosi</a> </p> <a href="https://publications.waset.org/abstracts/175772/a-new-genus-and-species-of-agriotina-laporte-1840-coleoptera-elateridae-agriotini-from-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175772.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">84</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1454</span> Regulation, Supervision and Accounting Conservatism: Interaction of the Three Pillars of Basel II to Achieve Quality of Reporting Earnings in Worldwide Banks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Diaz%20Sanchez">I.

But how these three pillars interact each other is the main research question that is not empirically solved. We analyze how regulatory and supervisory regimes interact with the market discipline measures, such as listing status, ownership and market concentration using a sample of 14,651 bank-year observations covering 54 countries over the period 1997-2009. We evidence that regulation a supervision and extend on which they are enforcement is a strong mechanism to achieved accounting conservatism in those countries or situations where the market discipline fails. Generally, the supervisory power reinforces the effect of listing status, ownership and concentration on conservatism, while capital regulatory mitigates the effect of market discipline on conservatism. This paper may contribute to debate about the mechanism introduced by Basel III that strongly increases the regulation, his enforcement, and the supervisory power after long deregulation period. Although Market discipline is relevant to achieve the financial stability, strong Pillar I and II can ensure the quality of the accounting earnings to prevent bank failures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accounting%20conservatism" title="accounting conservatism">accounting conservatism</a>, <a href="https://publications.waset.org/abstracts/search?q=bank%20regulation" title=" bank regulation"> bank regulation</a>, <a href="https://publications.waset.org/abstracts/search?q=bank%20supervision" title=" bank supervision"> bank supervision</a>, <a href="https://publications.waset.org/abstracts/search?q=loan%20loss%20recognition" title=" loan loss recognition"> loan loss recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=market%20discipline" title=" market discipline"> market discipline</a> </p> <a href="https://publications.waset.org/abstracts/92418/regulation-supervision-and-accounting-conservatism-interaction-of-the-three-pillars-of-basel-ii-to-achieve-quality-of-reporting-earnings-in-worldwide-banks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92418.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">172</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1453</span> Hydro Geochemistry and Water Quality in a River Affected by Lead Mining in Southern Spain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rosendo%20Mendoza">Rosendo Mendoza</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Carmen%20Hidalgo"> María Carmen Hidalgo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Jos%C3%A9%20Campos-Su%C3%B1ol"> María José Campos-Suñol</a>, <a href="https://publications.waset.org/abstracts/search?q=Juli%C3%A1n%20Mart%C3%ADnez"> Julián Martínez</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Rey"> Javier Rey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The impact of mining environmental liabilities and mine drainage on surface water quality has been investigated in the hydrographic basin of the La Carolina mining district (southern Spain). This abandoned mining district is characterized by the existence of important mineralizations of sulfoantimonides of Pb - Ag, and sulfides of Cu - Fe. All surface waters reach the main river of this mining area, the Grande River, which ends its course in the Rumblar reservoir. This waterbody is intended to supply 89,000 inhabitants, as well as irrigation and livestock. Therefore, the analysis and control of the metal(loid) concentration that exists in these surface waters is an important issue because of the potential pollution derived from metallic mining. A hydrogeochemical campaign consisting of 20 water sampling points was carried out in the hydrographic network of the Grande River, as well as two sampling points in the Rumbler reservoir and at the main tailings impoundment draining to the river. Although acid mine drainage (pH below 4) is discharged into the Grande river from some mine adits, the pH values in the river water are always neutral or slightly alkaline. This is mainly the result of a dilution process of the small volumes of mine waters by net alkaline waters of the river. However, during the dry season, the surface waters present high mineralization due to a constant discharge from the abandoned flooded mines and a decrease in the contribution of surface runoff. The concentrations of dissolved Cd and Pb in the water reach values of 2 and 81 µg/l, respectively, exceeding the limit established by the Environmental Quality Standard for surface water. In addition, the concentrations of dissolved As, Cu, and Pb in the waters of the Rumblar reservoir reached values of 10, 20, and 11 µg/l, respectively. These values are higher than the maximum allowable concentration for human consumption, a circumstance that is especially alarming. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20quality" title="environmental quality">environmental quality</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogeochemistry" title=" hydrogeochemistry"> hydrogeochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20mining" title=" metal mining"> metal mining</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20water" title=" surface water"> surface water</a> </p> <a href="https://publications.waset.org/abstracts/146855/hydro-geochemistry-and-water-quality-in-a-river-affected-by-lead-mining-in-southern-spain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146855.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1452</span> Board of Directors of Small and Medium-Sized Enterprises to Go Public: Characteristics and Moderating Factors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa-Jos%C3%A9%20Palacin-Sanchez">María-José Palacin-Sanchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Filippo%20Di%20Pietro"> Filippo Di Pietro</a>, <a href="https://publications.waset.org/abstracts/search?q=Reyes%20Samaniego-Medina"> Reyes Samaniego-Medina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article examines, in an institutional context such as Spanish one, the corporate board structure characteristics and determinants in entrepreneurial firms to go public. Specifically, it explores these issues through all the initial public offerings in the Spanish Alternative Equity Market (MAB), which is a market segment for smaller growing companies. The results show that: a) firm size, age of the company, and the reputation of the auditor and the nominated advisor and Corporate Governance Code favour a larger and more independent board structure that enhances its monitoring functions; and b) leverage, opportunities of growth, sector risk and ownership by executive directors all lead towards a smaller broad of directors where the role of entrepreneurship provided by executive directors remains crucial. This reflects the delicate balance of power between small-business entrepreneurs and financial equity market forces, which demand more transparency and monitoring in the companies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=board%20composition" title="board composition">board composition</a>, <a href="https://publications.waset.org/abstracts/search?q=board%20size" title=" board size"> board size</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20governance" title=" corporate governance"> corporate governance</a>, <a href="https://publications.waset.org/abstracts/search?q=IPO" title=" IPO"> IPO</a>, <a href="https://publications.waset.org/abstracts/search?q=SMEs" title=" SMEs"> SMEs</a> </p> <a href="https://publications.waset.org/abstracts/65556/board-of-directors-of-small-and-medium-sized-enterprises-to-go-public-characteristics-and-moderating-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65556.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">400</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1451</span> The Conception of the Students about the Presence of Mental Illness at School</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aline%20Giardin">Aline Giardin</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Rosa%20Chitolina"> Maria Rosa Chitolina</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Catarina%20Zanini"> Maria Catarina Zanini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we analyze the conceptions of high school students about mental health issues, and discuss the creation of mental basic health programs in schools. We base our findings in a quantitative survey carried out by us with 156 high school students of CTISM (Colégio Técnico Industrial de Santa Maria) school, located in Santa Maria city, Brazil. We have found that: (a) 28 students relate the subject ‘mental health’ with psychiatric hospitals and lunatic asylums; (b) 28 students have relatives affected by mental diseases; (c) 76 students believe that mental patients, if treated, can live a healthy life; (d) depression, schizophrenia and bipolar disorder are the most cited diseases; (e) 84 students have contact with mental patients, but know nothing about the disease; (f) 123 students have never been instructed about mental diseases while in the school; and (g) 135 students think that a mental health program would be important in the school. We argue that these numbers reflect a vision of mental health that can be related to the reductionist education still present in schools and to the lack of integration between health professionals, sciences teachers, and students. Furthermore, this vision can also be related to a stigmatization process, which interferes with the interactions and with the representations regarding mental disorders and mental patients in society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mental%20health" title="mental health">mental health</a>, <a href="https://publications.waset.org/abstracts/search?q=schools" title=" schools"> schools</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20illness" title=" mental illness"> mental illness</a>, <a href="https://publications.waset.org/abstracts/search?q=conception" title=" conception"> conception</a> </p> <a href="https://publications.waset.org/abstracts/60013/the-conception-of-the-students-about-the-presence-of-mental-illness-at-school" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60013.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">469</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1450</span> Effector and Memory Immune Responses Induced by Total Extracts of Naegleria fowleri Co-Administered with Cholera Toxin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Q.%20B.%20Maria%20de%20la%20Luz%20Ortega%20Ju%C3%A1rez">Q.

At present, there are no treatments available for MAP, and the development of effective vaccines that generate long-term immunological memory allowing protection against MAP would be of great importance. The objective of this work was to analyze the effector and memory immune response in BALB/c mice immunized with total extract of N. fowleri co-administered with cholera toxin. In this study, BALB/c mice were immunized four times intranasally with ET of N. fowleri adjuvanted with CT with or without booster at three months and were challenged or not with the lethal dose of N. fowleri, determining survival, the humoral, effector and memory response, by ELISA and flow cytometry techniques. The results obtained showed that the survival of mice immunized with booster had 60% protection compared to the group without booster, which obtained 20% protection. Evaluating the humoral response, it was found that both IgG and IgA levels were higher in sera than in nasal washes in both treatments. In the cellular response, the increase in the percentage of positive cells was found for effector T and B lymphocytes in the nasal passages (NP) in the group with boost and nasopharynx-associated lymphoid tissue (NALT) in the group without boost and lymphocytes only. B in both treatments, as well as in memory cells treatment with boost T lymphocytes in PN and NALT and without boost in cervical lymph nodes (CG) with respect to B lymphocytes, in PN, GC and NALT in treatment with boost and NALT in treatment without booster. Therefore, the involvement of the effector immune response and memory play a fundamental role for protection against N. fowleri and for the development of vaccine candidates. <p
